What is your motto or main principle in life?

Strike while the iron is hot! Be happy always! Put God first in everything! These are just some of the motto's or principles that we people hold on to. As for me, my favorite motto is "You can do anything you want to do...that is, if you are with God". There's a certain verse in the bible relating to this motto, though I forgot the specific numbers already. I hold on to this motto, everytime I feel like I can't do the thing that I need to do, or everytime doubt comes in to me. This makes me stronger specially during hard times. This translates my thoughts from negative to the positive side. By thinking about this motto always, specially in times of trouble, I am able to surmount any difficulty that comes my way. This helps me think that in my battles in life, I am not alone. There is someone who is far greater than all of the difficulties that I am experiencing. And simply knowing that, just makes me believe that I can do it, whatever it is that I'm supposed to do. If we think, that we can do everything on our own, even without God's help, we are just bound to nowhere, but FAILURE. Believe me, you have to put your plans, your dreams and aspirations in God's care so that you can be assured that everything will turn out just as it is supposed to be. Fear greatly affects our life. As much as I hate to admit it, I observe that its the main stumbling block that is keeping people from being successful in their lives. So, instead of letting fear dominate our emotions, we just have to believe that nothing is impossible with God. If it seems like impossible for us to do, there is someone greater than us who can and who knows how to make things turn out just fine. And I bet, you know who it is!
