I have this problem quite often, specifically I'll frequently decide I won't like something before I even try it, even if historically I've had enjoyment from it.
Often I just force myself to start, sometimes that's setting a line in the sand "I'm going to watch YouTube until 15:00 and then we're going to do X" other times is physically forcing myself (setting alarms, sleep timers, etc..)
I don't really have a magic bullet unfortunately beyond "Just do it" but honestly getting over the hump is 99% of the problem.
On the support side, there are enterprise distros (red hat) but the community support honestly is top notch. I know windows has support but I’ve never really needed it day-to-day or had a situation where having access to support on Linux really would have been helpful.
Development side - I find Linux outpaces windows for what I do, plus a number of tools are just built in. Plus Jetbrains IDEs are Java anyway and run fine there.
Browsing, i assume you mean the web? This is functionally identical.
I personally like Linux cause it’s tracker-free and more customizable. I prefer ZSH to power shell and I like that my desktop and server are running the same platform preventing strange bugs between environments.
