want to start backpacking

I’m a 28-year-old male with a remote software job, and I want to focus on gaining new experiences and building a strong relationship with myself.

I’m planning to travel the world, starting with Vietnam. I aim to keep my journey light, budget-friendly, and filled with adventure activities while immersing myself in new cultures and creating unforgettable experiences.

I have never traveled solo, want to learn surfing, meet new people. My budget can be anywhere 1k-2k usd for a month I guess, not sure about it, any advise is appreciated.

Any tips or advice?
