ほうがいい

「ほうがいい」is used to give advice, indicating that it would be better to do something (たほうがいい), or it would be better not to do something (ないほうがいい). These sentence patterns can sometimes come across as forceful or imposing on others, so it's important to consider the context when using them.
When ほうがいい is used with a verb in the dictionary form, it gives advice from a neutral standpoint, suggesting what is generally considered preferable. When ほうがいい is used with た, it gives a stronger, more personal advice.
「ほうがいい」can also be written in kanji as「方がいい」.
