Well I've finally arrived to the point where I'm ready to change my life - I'm taking plunge and going for Master Gardener certification program that will start this fall/winter. For past 20 yrs I've worked in corporate world of Telco and industry and past 10 yrs as project manager, and I think I'm ready to take a step back and focus more on my personal well being and do something I really enjoy - gardening, farming etc. Obviously I will keep working full time as I do transition and education in next year or two, but the plan is to start doing more weekends/part time in evenings in nurseries or at the farms. This is what makes me happy, even if it's more physically tiring but mentally so much more rewarding.
Is it the right choice? Well, time will tell. At any rate having more knowledge never hurt anyone.
