In the past two years i have been hellbent on learning to knit, sew, photography (all petered out after initial obsession)
But even larger in the last 4 years --- started and abandoned my own home business, joined a seminary to become a priest (still kind of in that but my 'stick-to-it' has totally died), started many large websites that ive left to rot, began to lead Meditation groups and then abandoned that... list goes on.
