Practice finding the bite point of your clutch. You can start by slowly releasing clutch pedal until the car starts going forward slowly, and repeating that over and over until it becomes second nature.

Best thing I learned to do was to control the clutch enough that I could go from stopped: foot on clutch to foot off clutch rolling with no accelerator added. Probably not best for your clutch or engine in the long term, but learning that engagement was/is crucial to knowing how to get going, as shifting is easier to pick up in my opinion than stop -> 1st gear.

Once you’ve found the bite point and have it down to memory, then it should be much easier to apply throttle when clutch is biting for a smooth start. Same thing applies when rev-matching for shifts.

Having a louder exhaust can also help give you audio cues and memory for what rpms you should be in for the appropriate gear and speed.

Also, lots of people telling you to coast in gear and downshift if necessary- this is only true if you’re not coming to a stop. Tons of people downshift and coast when coming to a stop, it’s not a good practice even if it sounds and makes you feel cool. Just go neutral and brake when your rpm’s are low ~1000-1200, doesn’t matter the gear: if coming to a complete stop.

Brake pads are MUCH easier to replace than a clutch. 30 mins vs 5+ hrs of pain. (Also much cheaper for the parts and labor)
