Who you want to be cannot be who you will be tomorrow.
Who you want to be has to be who you choose to be now.

You know that no one has instant control over the future.
You know that when that future time comes, you will not instantly change into that person you want to be.
You know that these things take time to develop.
You know that these things don’t develop if you don’t take action.
You know that you can only influence the present moment, nothing before and nothing after.
You know that the only the only thing that can influence the next moment, is the result of the present one, and what you do in that next moment.

So the only thing you can do is to influence the present moment the best way you can, and let our moments build into where you want to be eventually.
The only thing you can do is to be as close to that person you want to be eventually right now, so you can practice being that person, and get closer with every passing moment.

The are no guarantees for the future, but this is the only way you stand a chance.
