Thank you. It was a helpful guideline. Yet, to give more specific information, I'm a freelance landscape photographer quite renown in my country. Most of the procrastination is work related, due to the character of business. It could be summarized as indefinite & volatile schedule - too much freedom of choices - low income - medium social reward. For others, it must be one of the most exciting jobs to be doing. Yes, I appreciate but with some reservations. Actually, it's problematic & stressful more than being exciting; because of high expectation, lack of roadmap for future, difficulty in proper goal setting, and inability to gauge my ability despite of obvious numerous success markers.
I've always been prone to depression for no apparent reason (possibly existential depression with biochemical background), an obvious high IQ - low social ability type, and was diagnosed & treated for OCD when I was a teenager. I no longer show any of the obvious OC behaviours, but it has likely been transfomed into OCPD unfortunately, rather than having completely wiped out.
Too much freedom of choices gives me problem as well as the opposite case. Same applies for stress level. I've found that some extent of structured lifestyle is better, analogous to walking in a valley to a certain destination rather than being in the middle of an ocean with no sense of direction.
Each time I sit in front of the computer to either process photos, or write an article, I come across with questioning their value in the context of 'meaning of life'. Instead, lingering with trivial subjects gives a temporary relief from anxiety, but then it rebounds worse.
How can I just concentrate on what I'm meant to do? Maybe an external force?
I'd be happy if you may elaborate your answer in the light of this extra information.
