Welcome to Steemit @cekdowon , it is a pleasure to have you join us. I myself have spent a great deal of time working on vehicles and doing mechanical work. It can be very hit or miss like you said, with profit or income being sporadic at best. I wish you much success and luck in your line of work and on the Steemit platform.

I'm sure you will find Steemit offers more than just a means of making extra money, it offers a great community to engage in and become part of. The things you will learn on here, the connections you will make and the changes in life that can occur here cannot have a dollar figure on them, they are priceless. However, if you learn the platform and how to post, you can make an extra income for you and your two children. By the way, I am deeply sorry about the mother of your children!

If you need any help with anything on here, please do not hesitate to ask me or my friends @greetersguild. We are here to not only introduce you to the platform and many amazing people, but to educate you and teach you anything you'll need to know to be the best possible Steemian you can be! I myself do a great job at teaching my peers, so you are guaranteed to be in good hands! Please, feel free to swing by and ask anything you'd like! Also, be sure to enter in this contest event here to gain a great deal of exposure on your work, network with the community and possibly win a great prize.

I hope to hear from you soon my friend!
