True.
I love what I do to the point of working till my hands literally buckle due to cramping.
Sweating for 10s of hours and yet I still want to keep going on but my body gives up.
Same when i work in my other field. Keep at it till you break it down to elementary level.
Rewards come in many shapes and sizes, e.g. I also combine all my skills sometimes.
Its very relaxing, and rewarding, monies will follow, I find that money chases after honest work, If you start chasing money, you end your journey and become a dead statue.
