Ask HN: What to do when your technical ineptitude is hurting startup progress?

Hi everyone, Harj Taggar said in a YC YouTube video that you should learn an adequate level technical skill sufficient to build an MVP yourself. I have done that to the best of my ability, but I cannot learn fast enough about each aspect of my product to maintain a healthy speed for iteration and improvement. I feel like hiring someone would be like lighting a very short fuse (I could afford to do that only for about 2-3 months), but by myself I am moving so slow I can't keep up with user feedback. Speed or a longer runway. Which is more valuable? Thanks!
