Do you ever take on projects you’re not qualified for?

For others, not for a long time, but when I was younger (and hungrier) I did. Now that I am a little bit wiser and much older... I don't feel it is worth doing as most of the times I did it, I ended up putting in way more time and effort than I estimated and ended up making far less per hour than even a minimum wage job would have paid.

For myself, I still do. The most recent was buying a bull dozer and backhoe from an auction eventhough I had zero experience operating any heavy equipment. I should note that for the first year using these I had noone else around me and on my own land so I was not risking hurting anyone else or damaging anyone's property other than my own.

I think it comes down the morality of making promises to other people and potentially not being able to fulfill them.

If someone asked me to do a project and after I explained that I did not currently have the skill set to do it but thought I could figure it out, and they still wanted me to take it on. Maybe I would consider it but that would be a big maybe. Honestly I am more the asker than the doer these days.

Sure, just dont blatantly lie, or take something on that you don’t even know the required skills for. Or you might risk taking on impossible requirements (e.g. IOS app that wont be allowed by apple)

That’s the only way to improve- do something that’s beyond your current skill set.
