if you think about it. YOUR life is your decision. If you want it to be too short it will be. You make your own decisions to do things. YOU make time for things, you make space for things and you are willing to do things you need to do. You should always know what you want to do in life, If not, then, life is never too short for those who don’t have a plan. Having this, you'll know if it is or not. It all depends on your way of life. Nothing and no one will make your life longer nor shorte, better nor worse, easier nor harder but yourself.
Life is about learning to become better, learn about your mistakes, loving the most of you as you can and thinking before you act. If you dominate those things your life is completely fine, not too short nor too long. It depends on you if you want to succeed in life and how.
In life you have to be ready for anything that comes to you. Never expect the worse, never the best, just be prepared for anything. Life surprises us when we least expect it. Make sure your happy with your life and your decisions because at the end of the day they will keep being your decisions and the actions they cause are because of you and only you.
