My interests are like that other meme that got shared here recently, lol. I'm a jack of many, many trades, and I can't ever seem to complete projects I start, though I am trying more now.
For people like me, being stuck monetising a single interest strikes this deep sense of unease in me. I've been working a few years now, and I've decided to stick to something I'm not passionate about, but I can do the job to my abilities and put a lid on at the end of the day.
Anything else would probably consume my thoughts and leave me feeling mentally exhausted. It's like task paralysis, but worse.
I forget if Vyvanse is available in my country, or if it's only available in longer effect doses here. I've also heard about Concerta (is that the name?) but so far I've only tried Ritalin and it works pretty alright if I'm not overstimulated when it starts kicking in.
I have gotten overstimulated when I went out shopping once while it was in effect. Not a pleasant experience, but definitely a new one.
That's a pretty interesting fact about Vyvanse though. What's the window of effect for the one you take?
