I'm a 27yo European who basically has 6 free months of time before continuing my education.

Since I've swallowed the pill, I'm on the path of self improvement and I don't want to "lose" these 6 months.

Basically I'm asking for some suggestions on how to spend my time effectively these coming months.

Obviously lifting, eating well and reading are no-brainers. Also I'm on a bit of a budget since I've spent a lot of money on tickets for some festivals and a small trip to another country.

Hoping to get some useful suggestions.
