Leaf Blower Revolution - Idle Game

In my experience, the simplest way to earn these achievements is by investing in a Converter. This tool allows you to passively upgrade resources, starting with Green (Regular) Leaves and progressing to Gold, then Platinum, Bismuth, Cosmic, Void, and beyond. Using a Converter that automates the process makes it an efficient and hassle-free method.

Passively or Actively, this can be done over time. Easy to obtain.

In the upgrading Leaf Blower section you can buy upgrades and one of the earliest one can be obtained as you unlock Gold Leaves and use that currency to purchase the Leaf Blower.

You obtain this achievement when you upgrade through the Gold Leaves section and get Portals. A new tab will open up where you can reset your progress and practically start all over again, but with additional bonuses. The process is called Prestige.
