Can I have some advice?

Hi-- I'd start with a very open mind re opportunities. I’d not discard any field at this point, especially because-- e commerce and dropshipping are avenues to present & deliver goodies from your business and not a business in itself, unless you are FeDex, for example.

Folks focus on selling items *cheaper* than others; I’d suggest also to explore selling items that are *better* than other sellers, and mostly items that are *different* from others-- either things that solve a problem differently or are uniquely attractive for other reasons. To find good ideas, write down a lot of ideas without any filter, and in a second step select 2-3 using a realistic approach. There's a lot of trial & error involved, so try a bunch of things, but just a few units each, see what works, repeat, ignore the rest. Watch each penny to make sure you are profitable. Persevere, persevere, persevere.
