Startups are businesses. You need business acumen and people skills, neither of which are engineer qualities. If you do decide to do a startup, realize your first hire is not yourself, but the CEO who will handle the initial pitch, finance and all that non-engineering jazz. Also know that your priorities as an engineer are out oa whack with that your startup will need, unless you're already used to doing things in an agile manner.
But realize that the traditional startup might sound sexy but it sucks. If you can at all bootstrap it, do it that way. If you never have to pitch to a VC, then that's the best outcome for you, even if it takes a little longer. VC funding is only when you have hurdles to entry that you can't cross on your own, or you are racing to market because of a timeline.
Once you bring in a VC, you no longer own the business, they do, despite whatever equity agreement you have.. You wanted a start-up to be your own master, but having other people's funding makes them the master.
