"Old job" anxiety

The longest I have ever been in a company is 2.5 years. I have reached the 2 year mark a month ago at my current job, and I can't help but feel a little... antsy. It's just me being human thinking the grass is always greener. I mean, who can beat the following perks?

• Summer Fridays beginning early May through end of September
• Free haircut and color every few months
• Free beauty products
• "Work at home" one day a month
• Breakfast every few weeks
• Team lunches every month
• 10 minute commute - walking
• Flex schedules and...
• 6 months of maternity leave! (No wonder everybody at work is pregnant)

Maybe I'll stay a little bit longer?
