Buy Agilent 34401a for better accuracy and consistency for calibration of Temperature sensors.
Find EEVBlog and start reading and looking at the pretty pictures.
Build first two voltage references and find out about drift and long term stability.
Find this slightly insane bunch of TEA members.
Buy inferior but workable Feelcrap signal generator and buy first vintage HP counter to check it's frequency.
Buy Two 34970a data loggers to commence recording of these knowing that you need to build better references.
Decide the 34401A has some short comings on low ohm measurements - Buy a Quadtech Milliohmeter
Start buying bits for two LTZ1000 references.
Buy a 121GW because you know now your existing multimeters are really cruddy.
Randomly Buy two power supplies a Manson 3030 and an Agilent 6632B
Buy a slew of Good Quality Decade Capacitance and Resistance boxes (6).
Because you own a signal generator and are sick and tired of your Hantek USB - Buy a 100Mhz Micsig
Buy wine fridge not to put wine in but to house the aforementioned references in at a nice stable 25 degrees.
Decide you like the look of Nixies and 'need' a DC voltage source - Buy a 740B
Happen across a poor forlorn Pommie Nixie counter in the USA in need of some TLC - offer it a better home.
Beacause the 740A manual said I needed one buy a 735A voltage standard.
While looking at voltage standards you find an Valhalla AC voltage calibrator whose freight bill alone would feed a family for two weeks.
Decide you really like Nixie Tubes and in particular counters buy a 5326B
Because you now own three slightly older Frequency counters and are unsure of their accuracy - buy a gpsdo.
This is sort of my last years decent into TEA
Now Better Sig Gen, SA, 3458a ...........
