One of my life principles is to be always growing.
In whatever you engage in life, do it with the mindset of growth. Try to be a little better than you were at the start.
Growing is a key part of happiness. We as human beings are built to strive for things, the more we strive the happier and fulfilled we are.
When you have this mindset in small areas, you will have the mindset in large areas.
When you are taking care of your home, try to make it a little better every time.
When you are running on the treadmill, have the perspective that you will run a little faster every time.
When you take up a new hobby, go in with the intention of being the best you can be.
When you strive in the small things, you will strive in all things.
