> I subconsciously tell myself 'If I just used Linux, I could be like them!'.

Your intuition was right.

Learning to fix issues in Linux gives you long-term transferable valuable skills in troubleshooting and far-reaching knowledge. Learning to fix Microsoft's latest fubar gives you nothing, unless you're in corporate IT fixing other people's computers.

You'll become more confident and niggles won't bother you that much.
