As an honest Adsense publisher, you are likely to send an email to Google Adsense support with the URL of the web page where you clicked your own ads and probably the reason (like the mouse was so sluggish).
Yes, it's important that you don't click your own Google Ads else there's an element of risk that Google may disable your Adsense account but do not get too worried if the click was made due to an error.
Here's a standard response from Adsense support when publishers make honest confessions:
Thanks for letting us know about the clicks on your ads. We appreciate your honesty and your efforts to keep your account in good standing.It further says - If you were clicking your ads out of interest or to see who was advertising on your site, we suggest the AdSense preview tool as an alternative. This tool will allow you to check the destination of ads on your page without the risk of generating invalid clicks.
Although publishers are not permitted to click on their own ads for any reason, we do understand that accidental clicks may occur, so we don't require that you contact us every time you click on your ads.
AdSense Publisher support team also says - "Because we closely monitor all account activity using engineering systems and thorough human analysis, chances are we've already detected your clicks on your ads and discounted them. While these clicks still show in your reports, we filter out their associated earnings so that advertisers aren't charged."
