There's a pub in England with that sign over the bar. So simple, and so true. If you wait until tomorrow to start what you want today, then you'll never get it.
The only time that you have is today. Tomorrow does not exist and yesterday neither.
If you keep on saying I'll do, you'll end up doing nothing.
Start now! Because you only have this moment to do it.
Yes, you can't do it all right now, but you can still do some of it. And you'll keep on doing it if you start today.
It takes 27 days to create a habit. So if you want to achieve something in your life, you should start to create good habits right now. And keep building these goods habits for 27 days, after that it will go on almost on automatic.
¸The time that you didn't use will never come back. It's gone. And you can't do anything about it. It's too late.
Don't wast any more time thinking about what you should have done and focus on what you can today. Focus on today.
