On login redirect to the user's account page using 'Rules' module?

Steps

1. Create a new rule
   First we have to start a new rule. For this go into the rules admin center, click on "Triggered rules" and on the tab "Add a new rule". Select the event "User has logged in", set the label "On login redirect to account page" and click "Submit".
   Now we have created a new rule, which is still empty. Every conditions and actions that we add to this rule, will be evaluated on the event "User has logged in".
2. Create the redirection action
   To do so, click on the "Add an action" link, under the section "System", select the action "Page redirect" and click on "Next" button. In case you have the token module installed, the "Page redirect" action allows you to use token replacements. This allows us to place the user's id in the redirect path.
   So call the action "Redirect to the users account page" and set the path user/[account:uid]. Then activate the checkbox "Force redirecting to the given path, even if a destination parameter is given" - which is necessary, because drupal sets always a destination parameter to the current page, if a user logs in. So, that our redirection applies, we need to activate this. Check the option, and and click on "Save" button.
   That's all. Just log out and log in again - you'll be redirected... :)
