There is money in gardening - I have friends that are very successful at it, and are still hands on, picking and planting the plants - while making more than enough to live a happy life.
My father loves drawing and making stuff, he is a pretty damn successful stage designer.
You have to love what you are doing AND be good at it AND good at selling yourself. But if you can crack that you really can love getting up each day. I know I do, and I know most of my friends and family do.
My richest friend works 60 hour weeks to have a great car parked outside his office and to support a stunning home he never 'lives' in - and he will tell anyone that no only does he hate his job, he isn't happy. But he really thinks having more (holidays, watches, suits, etc.) will make him happy, but they haven't yet...
If I did what I loved, I'd be in the garden or knee deep in solder.
I do what I have to do, so I'm chained in front of Visual Studio.
