A useful perspective from Japan is to treat supplements as background infrastructure, not a project. Many people focus on consistency—small daily habits that are easy to repeat—rather than short bursts of intensive use.
This mindset can reduce "cycle buying," where you purchase products during stressful periods and stop when life becomes busy. A routine that fits your lifestyle in Singapore—work hours, meals, travel—matters more than an ideal plan that you cannot maintain.
If you choose to use supplements, consider a periodic review: what you take, why you take it, and whether it still fits your life. That review is often more valuable than adding new products.
