Understand.
I learned how to do a lot of things because I was poor so I get it.
I picked up a lot of my first tools at garage sales and flea markets and learned how to do a lot of things by researching it. A lot of it before the internet was a thing and meant going to the library or local garage and asking questions.
Don’t cut yourself short on what your abilities are. Saying that you have never done something before is the reason you can’t do it, is just an excuse for not being willing to try. Lack of knowledge isn’t an excuse, just a temporary situation until you gain the knowledge.
As for time, I personally have four kids and work full time, so I get being busy, as do many of the folks on here. It’s just a matter of finding the time sometimes. I’ve been underneath my car in 2°F weather at 12:30am because that’s what it took to get the vehicle back up and running so I could get to work the next day.
The person who isn’t willing to risk making a mistake, is a person not willing to learn new things. Everyone in this forum had to learn what we know. Some had opportunities to learn earlier in life than others, but everyone that is trying to help you has had to learn stuff along the way. Also, you are not the only one that had to pinch pennys to make it from paycheck to paycheck.
When people on this forum offer up help in the form of guidance or suggestions and the only thing we get back are excuses as to why it can’t be done, they will stop offering up assistance. You are asking a lot of questions, which is fine, but you will not find an “Easy Button” for most of the issues you are having. They will take time and some money to work through. We will be here to help you along the way, but you have to be willing to listen, learn and most of all be patient as you get the time, tools and money to address the issues.
