Most of your time is spent waiting.
Waiting to graduate, waiting to be promoted, waiting for your business to prosper, waiting for your child to graduate, waiting to get married, and waiting to retire.
Most of the time, it's waiting to get to work, waiting to get home, waiting for the train, or (like what I'm doing right now), waiting for the bus.
Don't just do something to pass time. Do something "meaningful” - to you and to other people.
Do something that will make you grow. Read a book. Listen to a talk. Pray. Meditate. Connect with yourself.
Do something that will make others grow. Write a blog post. Share your wisdom. Solve other people's needs. Create a business.
Don't just do something. Do something meaningful.
