To some extent, it depends on the context . Personally, I think you should give your startup 100%. I've had to make a similar decision before and chose that route for a few reasons:

1. for most startups, except with the exception of some lifestyle startups, it won't succeed if you give it 50%.

2. it matters to you, personally. leaving the comfort zone was, to me, a statement to myself that I'm committed to this and have no fallbacks. With this point, I was really influenced by that one HN post about how Alexandar the Great would burn the ships they used to go somewhere for war, basically to say "theres no retreat"
