First you have to ask yourself whether there is something that is holding you back... and if so, what would happen if you would let go? For example, are you scared that you will not achieve your goal? If that is the case, then you need to find out what you are doing when you are not thinking of failure. Are you hanging out with your significant other or watching your favorite T.V show? Life comes at us so fast, that sometimes we forget the daily things that make us happy. It is within these that we find our motivation... just like the sunlight that wakes us each morning. Focusing on something that makes you happy will slowly but surely help you let go of what was weighting you down.
