Best way to spend 3 days?

Iv got 3 days off work and my girlfriend is away for that time. IM ALL ALONE

I have 5 micro niches and im monetizing with adsense. They are mostly on page 2 of google.

My tools: Scrapebox, xgen seo, pen and paper, alot of strong coffee

I have around $20 to use for domains for new niches.

What do you guys think I should spend me 3 days doing?

(I will be spending 1-2 hours niche finding so I may make new sites but I also want to push my existing sites up in serps)

Take 3 days off and pop round JonnyRabbits ex's she ain't doing much either.

1. Find all your competitors backlinks then submit your site to as many of them as you can.
2. Make some youtube videos for your niche.
3. Download market samurai to help you find more niche ideas.
