Of course, things will go wrong.
Move on!
Don't let the little snags
affect the progress of your life.
Are you hurt from something? And has it been residing in your heart for long? Don't let your hurts rule your life. Don't curse them, don't nurse them and don't rehearse them. Instead, what you need to do is reverse them.
Of course, there will be problems and things can go wrong but you must move on. Just because you face problems, it doesn't mean that you should stop living your life. Life is all about facing problems, converting problems into stepping stones and moving on.
