How do you overcome major hurdles in your life?

Your avatar is the best answer. Surrender to Him. Put Him in the drivers seat. He will take care of all your problems. You just do your duty without worrying for the outcomes. No body is free from problems. Problems are there to make one understand that, this is not the place where we belong. We belong somewhere else and that place is with God. We have to purify ourselves to reach there. Thats the main objective of life. Once we understand the main objective of our life, the problems seem minature in form.

I put it at the foot of the cross for Jesus to carry. Because he knows much better than I. And way easier to deal with major hurdles in my life.

You are right. All have problems at one stage or the others. When problems stall your life, you have to pray god, change the strategies, rework and devote more time to solve the problem. A solution will be found to overcome the problem. Never you should keep worrying about the problem. If you do so, then worries take away much of your time.

I think it's important to have a support system for you to rely on. For example, family or friends are a great source for strength during difficult hard times. What doesn't kill you only makes you stronger.
