I worked out specifically what I wanted — which was to actually do stuff, because I wasn't actually doing anything anymore in life.
Since starting Ascended Mogul and Emperor: two new jobs, started a business, will be starting another business, have another money-making opportunity starting next week, renewed my interest in the stock market, started regular exercise again, regulated my diet, and renewed my interest in my two hobbies.
Subs work. But you need to define pretty accurately what you want to achieve, find the right subs for you — different subs work differently on different people — and take action.
