What I have learned over my 55 years on this earth is the key to success is following through on your commitments.
If you truly want to achieve something, you will commit; so once you do commit please follow thru.
I will caveat, however, to never let your dreams and commitments take priority over your family and faith. It is a balance you must recognize.
There may be times when stress enters the equation, but that is just a little fear trying to stop you from reaching your dreams.
I want to share a blog I wrote many years ago, but I believe it still holds true.
