1) Think Krishna to be your best friend and imagine that you are playing, walking with Him. Do all actions keeping Him with you. When you are alone, just think of Krishna and do not feel lonely. Keep in mind that He is always there with you, helps and protects you every moment.
2) When you are doing your homework, imagine He is sitting next to you and helping you.
3) You must believe in Him and believe that He will surely help you. He is always yours. He talks to you in your mind. Krishna never forgets you even for a single moment. The coolest thing is that nobody will know you are talking!
4) Don't think, "When I grow up, I will start remembering God." Start now.
5) Chant the Name of "Radhey Shyam" constantly and silently. Say "Radhey" within your mind when you breathe in, and say "Shyam" within your mind when you breathe out.
6) Avoid bad company.
7) Every night before retiring to bed, recall and count the number of wrong deeds you committed for the day and pray for forgiveness, whether it was done knowingly or unknowingly. Resolve to correct yourself and not to commit the same mistake again.
8) Give respect to everyone. Never fight with others and hurt anyone by your bad behavior. Realize that God resides in everyone's heart.
9) Never feel lonely or alone. Don't get angry. Try to be nice to everyone.
