Hi vasagan.
This is the main issue with many of us. I can give you a small suggestion if you feel like working on it you can take it. Try to make some source of passive income.
As your profile says you are a excellent photographer try to do small business with it there are many people who need a part time photographer try to find those people im your place and charge them some amount as well as you can do one more thing sell your photos on different stocks website. Or else make some youtube videoes it is time consuming don't know if you would have enough time for it or not. Last ly 3rd diea for you is to become ghost writer and write some great content for other website for sometime once you start earning good you can skip and get sponsored trips as well. Thank you hope it might help you a bit. Keep sharing your experience. Cheers.
