I'm 22 years old, and want to become the best version of myself. Physically, Mentally, Financially. I'm a introvert person but can have conversations in a group for some period of time. I just got out of college this year. I have a remote job that pays at least 25000 rupees. I major in Software Development. Not having a big strong circle of connections with rich mindset people seems to hold me back. I myself want to improve myself. Get rid of all bad habits. Build a good public image, and become widely known for better opportunities as well. Also looking for high abroad opportunities as well.
