A good idea implemented today is much better than a great idea implemented tomorrow. Just do it today, think today, plan today and start your action immediately. I don't know what tomorrow may brings but I have something is born today and I am going to continue tomorrow.
We may think that we have plenty of time and it's always on our side, but no time is running very fast and faster than one may imagine. Work faster, speed is what gonna keep you on track.
Just get started. When you believe your work is going to be done quickly, it will be done quickly, it's always your choice and your inner conscious is just going accordingly. When you do something out of urgency, you will work from your gut and the right thing will be done before you even think about it yourself!
The perfect time to improve yourself is always today and the best time to get everything done well is also this day. It's today not tomorrow.
