The proverb goes: The best time to plant a tree was 20 years ago. The second best time is now.
What are you waiting for?
There’s no better time to start.
Action is better than inaction.
Even if you “just” have 10 minutes. Start.
Don’t wait. There’s never a perfect time.
The best time is now.
Go for a walk.
Do 10 squats/pushups/lunges every day.
Do. The. Thing.
