Lifestyle Points (LP) are a type of currency used to buy premium items and to speed up actions. They can be earned, dug up, bought in the store for real money, or by watching videos and "viewing offers". Lifestyle Points are similar to Lifetime wishes in The Sims.
How to earn them
Players can earn LP by doing hobbies that give players 1 LP each time a Sim reaches level 6 in the hobby. Completing a hobby continuously can give players a lot of Lifestyle Points (e.g. By completing the Cooking Hobby, it gives you 5 LP. Using many sims as possible for this hobby will help complete the Cooking Hobby more faster). Some hobbies have either 2, 3, 5 or 6 LP.
The Cooking Hobby is one of the best ways to earn LP. The more sims you use for this hobby, the faster it is for you to complete its collection. It takes approximately about 10-15 minutes to complete it.
Players can also earn LP through planting a Life Point Lotus that costs real money (depending on the player's country and the amount needed) with the Jackpot being 500 LP. (The "Money Grows On Trees?" quest must be completed in order to unlock this).
Players can buy them through the Online Store with real money. In some updates, the LPs earned from hobbies sometimes decreases (for example, the Chocolatier Hobby previously had 3 LP when it first appeared in the 2016 Easter Update, but in later updates it dropped to 2 LP).
The last major way to get these is through town worth/level. Each level or town worth increase to hit a point would award some LP.
A minor chance based way is through ads.
Weekly Tasks always gives 3 LP per week.
Check Current Events incase of special events for some LP.
