Weekday Help and Victory Thread for the week of May 27, 2019

I lessened my TSP(401k) contributions because I wanted to save up more for a new home. I've finished everything with the house and now I want to max out my 401k this year. I've contributed about $3,000 so far and want to hit the $19,000.
This is doable, but I will have to sacrifice a vast majority of my paycheck. I have about $40,000 in a taxable Vanguard account. Would it make sense to get paid almost nothing from my paycheck to max out my TSP(401k) and every two weeks or so sell funds from my taxable Vanguard account to pay bills and expenses? Essentially I'd be just putting my taxable investments into a tax-deferred account in a roundabout kind of way.
