Assuming here that you are young and at the start of your career.
Budgeting and habits are more important than actual saving. Any ₹₹ you save today will take sacrifices, but those same ₹₹ will be earned in a day as your salary increases. Focus more on budgeting and not giving in to impulses.
Also, if you need to go into debt to upskill, do that. Do anything, whatever that will improve your future income. Degrees, education, courses, socialising etc. Take money from parents and relatives if possible and need to increase that 20k income asap somehow.
