If you want to change your life, you need to do something new and that includes making new friends. I can’t emphasise this enough.
Much of the access you get in life; much of the exposure, knowledge and new perspectives comes from people. It comes from a mentor who recommends a book, provides a reference for an MBA programme or introduces you to a potential investor. It comes from a friend who suggests traveling somewhere new or who invites you to their home and exposes you to a new standard of living.
We live in very closed worlds. Upbringing, religion and culture keep us there. Oftentimes, the only way to break free of tradition and experience new worlds is if a friend invites you in.
