Don’t bother buying jelly bean parts. Just buy what you need for a project and buy some extras and sorted.
I’ve got about 75kg of parts floating around and I couldn’t populate more than 20% of the last two boards I did from it.
Tayda are worth looking at for cheap stuff in bulk which isn’t crap.
The problem is sometimes I need a thing and I don't find it, such as mosfets and zeners lately.
The parts I have (or already ordered) are:
1- resistor assortment. 1280 pieces.
2- elec. caps assortment.
3- ceramic caps assortment.
4- lm358. I have x100 smd in a tube and ordered another 50 or so in DIP. Also ordered smd to dip adapter for them.
5- lm324. ordered around 50-100, I don't remember.
6- diodes assortment. IN4001~7.
7- LEDs x500 5 colors.
8- low power npn and pnp transistors.
9- IRLIZ44 x10 pieces.
10- BD437 and BD438. x10 of each... nice higher power transistors.
11- power resistor 1R 50Wat. x5
12- GD900 thermal paste. x5
13- small heatsink. x2
14- IRL640A. x10
15- mini dc-dc boost converter. x5
16- mini dc-dc buck converter. x10
17- buck-boost module. x1
18- buck module x3
19- LM317. 5 modules and 20 bare pieces.
20- RGB LEDs x20.
21- header pins... good quantity.
22- on\off buttons. x5
23- heat shrinks... a small kit (enough).
24- silicon pads, small 30 pieces.
25- tactile push buttons. x100
26- pots (different sizes and values).
27- 10-turn pots. x3
28- screw terminals x20.
29- Arduino pro mini x5
30- Arduino nano v3. x3
31- mini dc voltmeter module x6
32- prototype boards... a kit of different sizes.
33- altoid-like tins x3
34- aluminum enclosure x1
35- plastic instrument enclosure x1
36- plastic box enclosure. x1.
37- solder wick. crap brand and never worked!
38- wires kit.
39- panel meter. x1
40- ac-to-dc module.
That is my collection without mentioning tools and so on. Looking forward to enhance it with your feedback.

I aim to do the following projects:
1- lab bench power supply (uses the instrument enclosure, ac-to-dc converter, and buck converters...)
2- diy electronics dc load (aluminum enclosure + opamps + logic level N-MOSFET).
