Although the Lord's prayer is probably the greatest prayer known to Mankind, the Lord clearly didn't intend it to be recited. "Our Father who art in Heaven, hallowed be Thy Name. They Kingdom come. Thy will be done on Earth as in Heaven. Give us this day our daily bread..." He evidently worded it as an example of HOW to pray, not as the literal words to be used: Succinctly and briefly, remembering that God is in Heaven and we on Earth so that our words should be few. In other words, don't show off before God when in prayer, and don't pray to make a good impression with those around you. Better to pray with few words to God in secret than many words in public for the sake of impressing humans listening. Remember who you are addressing: You are addressing the One who has power to know what you will say before you say it.
When He gave the example of asking for daily bread - "Give us this day our daily bread" He was telling His followers to keep on asking for a daily dose, as it were, of the Spirit of God, which is to be His disciples 'daily bread'. He followed on to say how it is that God gives His Spirit to those who keep on asking just like a parent or neighbour gives bread to a child who asks or a friend who asks.
When He says in His example prayer "Forgive us our sins as we forgive those who sin against us" He followed it by commanding His disciples to forgive anyone they hold things against at the time they are praying so that God will see it and forgive the sins of the one so praying and forgiving. They aren't to be a mere recital of words but a genuine act of giving others forgiveness while there praying before God. Then God also forgives the one praying but He cannot be mocked. He forgives the forgiver and He gives the daily bread which is His Spirit to the genuine believer; not merely to the one only vainly reciting the words.
Keep it real, but the words of the Lord's prayer do teach us how to do so, if they are used in genuine faith, by the help of God's grace.
And when praying for another individual or group of persons, don't waste many words for no reason just to be praying; far better is just a few words you are sure God will hear and answer - a few words with faith - far better than many words in pretense and vanity. It is the outcome not the impression which counts. Be careful what you ask for in faith because if you ask in faith you will get what you ask, provided it is according to God's will. This is just as well because He wills what is good and what on the whole saves people, even though sometimes that involves a certain degree of evil, as when it is a prayer for justice or vengeance from Him against an enemy. Yes He does answer such prayers too, especially when the aggrieved one keeps on praying and praying for justice from Him. That also Jesus taught. But He did warn that people should bless and not curse because those who curse are liable to be cursed but those who bless will receive blessing. Be careful not to wrong anyone whose prayers God hears because their prayers might be for justice against you and God is unimaginably powerful. He is unimaginably loving too and unlike most people He has a special love for the poor and the wronged and all the more for those who belong to Him. They are bought by the blood of His Son, the Christ, so He will give them pretty much anything else they rightly ask for too. That might be justice against you, especially if you have caused them to to do wrong against their God. How we live our lives is a very serious matter with very serious consequences, whether we believe that or not.
If you do all this and He gives you what you asked for, remember to thank Him for it. If you asked half you life for something and He gave it you at last, all the more reason to spend the rest of your life thinking Him for it. Ask that your joy may be full. Giving genuine thanks to God for His answer is so fulfilling and one of the highest things in life, like caring for others. "Love the Lord Your God with all your heart, all your soul, all your strength and all you mind mind" and that includes loving Him with your voice, in giving Him credit and thanks for His love in what He gives to you.
