Sir, main issue is that you do not stay committed in difficult times. Everybody has few challenging areas in life and for you career is one of them. Career will be an area where you need to put in 150% hardwork for initial few years, and eventually it will give you satisfaction afterwards.
But you leave things when it becomes very difficult, or doesn’t go as per your expectation. What you have to do is pick 1 path in a wise way, and commit to it. If things wrong then you have to adapt and make them go right instead of making a U-turn. If you keep making U-turns, then you will reach nowhere.
No matter what career you choose, you will feel like you have to start at the bottom and work upwards without support, especially from your advisors or managers. If you get through these initial years of struggle, then your career will be financially rewarding.

A job will be good for you, rather than business. Because you lack commitment and discipline, the job will feel pressurising or irritating or unsatisfactory, but if you run a business which you keep leaving midway, eventually you will lose all your investment. And in the initial years, a job will gradually teach you to stay committed and disciplined.

Some remedies to help you:

1. Support institutes which encourage women entrepreneurship and women vocational training. If any female ever needs help from you especially for her business, try to help and don’t keep expectations from her or try to extract any return from her.
2. Keep distance from women at your workplace. Be friendly as a colleague but that’s it.
3. Don’t argue with high level managers or other seniors.
4. Offer water to surya dev at the exact same time every morning (follow rules related to this, you can find them online).

5. Keep a maun-vrat on Sunday. If you can’t do it for the whole day, start by doing it at least for a few hours.
6. Keep a murti or photo of Lakshmi-Varaha bhagwan in your house temple and offer prasad and flowers every Friday. Prasad should be such that it has minimum 2 dishes and at least 1 dish should be green colour (Eg pista roll). If you can find a temple of this god, visit every Friday and do seva there – this will be an excellent remedy.
7. Keep maximum respect for all females as they are all devis.

She takes tension about things or gets stressed and anxious, which is one of the things disrupting the menstrual cycle. Speaking openly to friends/family will be good.
