I would rather die of exhaustion than boredom.
No idea where I heard this but it resonated with me. Be busy but be smart busy. Do what you do very well, with ENTHUSIASM and get to the top of the mountain.
Exercise the mind. Exercise the body.
Allow time for sleep to rest the soul. Then rinse and repeat.
Enjoy the mistakes as there will be many as I have learned the hard way. No plans go that well. There are many huge blips on the journey to the top of your mountain.
Smile at the humps in the road and carry on. No one really cares.
