What are the ideal ways to ensure that our code won’t hit Governor limits?

Few things we need to keep in mind while writing a SOQL Query:-

• Write code with collections so that for every record, you don’t need to write a separate query or separate DML.
• Reduce the count of queries and try to fetch all needed data in the same query than calling again and again to Database.
• Never write DML or query in any loop.
• Use @Future annotation to bypass Governor limit errors.
