Start with the easy stuff.

Get a free incoming Lightning Address from a provider and explore sending and receiving balances between wallets. 

Some options:
https://coinos.io
https://fountain.fm
https://stacker.news

Then find a wallet that you can use to connect to your Nostr client to send zaps. This would probably be different for you and me because location is a factor.

Ultimately I’d recommend setting up a self-custodial Alby Hub that’s completely integrated into Nostr and gives you everything you need.
