I'm not an SSF player, but some general thoughts that might be helpful.
- A good filter is a huge time saver in SSF. Take some time and set up a filter for your build, highlight bases you prefer and disabling those that doesn't matter for you.
- Have a plan of how you are planning to gear your character from the early on and spend currency to achieve them.
- Always have a goal in mind when you are farming.
- Divination cards and Vaal areas can offer earlier 6-links.
- Use 1500 fusing bench craft to make 6-link on a proper base instead of gambling.
- Be ready to focus on all content, even if you can't maximize the returns, since you will need various league currency.
- Harvest is your friend when you want to switch gear, but resistances needs fixing.
