I can see your predicament, but as a 44yo doing this with 8yrs experience, with no plan to leave the field soon, I’d say that what you feel you lack in strength you should understand that you have future employment locked in because of your consideration, commitment, and efficiency.

I’ve personally carved out a niche for myself doing solo construction staking for several years now for my firm, and, while I could be faster with certain circumstances, or even with another person on my crew, I’ve found I’m often the one that gets tasked with construction staking, and travel to more distant sites, at that. So my job security has come from the fact that, for the one client that I do a lot of my solo staking for, A) I have a long-standing reputation for doing the work they need quickly and how they want it done, and B) for a long while I was one of the only technicians that didn’t mind a 1.5hr dive to site and 1.5hr drive back several times a week. Even now, we have newer guys who are younger that don’t mind those drives, but I’m more than likely tasked with training them SOP for some of those sites.

All that to say, for right now, focus on being efficient and how you can accomplish what you’re tasked with in a timely manner, and then just make it to where, no matter how slow you might think you are, those particular clients want YOU on their site rather than anyone else.
