NOW , right now is the only moment that you have to make your dreams come true. Right now is the only time you have control over, because you can choose how you react to things, you can make decisions that can take you to where you want to go, and you can take action right now.
You need to accept that you can never change the past, what it is will always be.
As for the future, it is what it will be. Accept that it is unpredictable.
The only thing you can do is to realize that what you do today will determine how it will be. Make decisions today that will make you happy when tomorrow comes, decisions that will make you proud of yourself and decisions that will get you closer to where you want to be.
Let me repeat it, the present moment is all you have! It is right now that you can carve the future that you want for yourself.
So you messed up in the past, so what? Maybe you failed at something? So what, we all messed and we have all experienced failure. Dust yourself off and keep moving!
Never give up because you are closer than you think. If you give up, you will never know what life has in store for you. So, make this moment count! Make it count!
