This is one accurate and very interesting quote. Because you do. Every day when you wake up you get a new opportunity to change all these things about ourselves that we may not like, or thing we shall improve on. But the change doesnt have to wait for a specific occasion, it has to happen at different opportunities. Opportunities that allows you to think differently and act differently upon this specific opportunity. Life doesn't allow you change, nor does time, only you have the power to change who you want to be, and most importantly, what you want to be.
Some people are scared of making changes. But if you have realized the things that you have done wrong and things you can improve on, then why not?
Why not take the next second and change you life?
