need some stackadvice from the pros!

Hi folks, I'm in India and have started researching about nootropics and wanted to build my primary stack. Recently did a blood test and found I was high cholesterol as I am a fat fuck.

1. something to help me with stamina, I get tired easily if I have to climb stairs or anything. I think I have embodied laziness

2. Clarity and Focus at work, sometimes I get zoned out and stutter when I speak which usually in gen day to day life I don't

3. I have a lot of tasks lined up at workplace and have a lot of courses I purchased which I haven't even touched. Something that'll help me boost productivity

4. Maintain a positive mood.

Currently, I take fish oil (salmon 1000mg), neem tablets (1g), and d3+k2 (600iu). I tried Shilajit but I fear that it'll generate a lot of heat.Have added a B Complex pill as well. (added it as my body tends to generate a lot of heat and that causes abcess- in May, if I skip having B Comples, I'll be fucked one abcess goes another one pops so if anyone has figured a permanent solution for body heat, I'll be severely indebted) Occassionally, I pop a CBD pill 625mg mostly on weekends to get a high

Can anyone guide me and direct me to a post or video or if you can share some advice in the comments.

Thank you folks🙌
