To achieve your goals with passion, Are you sure of your dreams? If not sure, will be difficult to achieve. We must build confidence in ourselves, that our ideal will be accomplished by God's permission.
Hesitantly less sure, then you will not reach. Rest assured.
When you do not have the ability, it's not a hindrance to be sure. Now can not afford, but if want to learn will be able.
Not knowing the way is also not a barrier for sure, because if we want to learn, we will know how to pursue our goals.
The proof is sure that you will achieve it is you so eager to achieve it. You have to be confident if you can achieve your goals.
