How to check Reward Summary for All time, last 30 days and last 7 days for your account?

At the bottom of the Stats page, you can view the reward summary as illustrated below.

What is Delegations?

Honestly, my layman understanding about delegation is similar to making an investment 🤣 you select delegates (similar to a fund manager) and invest (delegate Steam Power ("SP")) and in return, receive interest/dividend payout in proportion to the amount delegated (return-on-investment). This is helpful if you are focusing on content creation and/or have a limited amount of time to go on Steemit. Hence, while you are away, you can still earn a some Steem Power.

Types of Delegations?

Incoming = you are the delegatee
Outgoing = you are the delegator

How to Delegate SP?

Well, I have no idea....I am still looking for a list of active delegatees to delegate to and hoping I can just click on their profile and select delegate and voila! but nopes.........Anyways, I searched and yet to go on to "Page 2 of Google"😅, I found a simplified yet witty post by @steemitguide ^{How to Delegate SP} THANK YOU

Step 1: Click on the Delegations Tab on the left.
Step 2: On the delegations page, click on the Delegate... button.
Step 3: The Delegate SP prompt window will pop up.
Step 4: Key in the username of whom you would like to delegate SP to (username without "@").
Step 5: Key in the amount of SP you would like to delegate to the delegatee.
Before proceeding to STEP 6, ensure all information keyed in is as you desired
Step 6: Click on the Ok button
The Confirm Delegation prompt window will pop-up, in case you missed out on the precautionary step before proceeding to Step 6.

If all is good and in order, Click on Yes!! I do 😝 Like a marriage, you are committed till death do us part. Nah........well, I read around that we can file for a divorce - retract back or the correct term would be undelegate SP ^{How to undelegate SP by @raised2b}

Select the Account Operations drop-down menu and click on it.

At the left-side of the Account Operations page, you can view today as well as the account transactions for the last 7 days. You can filter to view all In & Out transactions or only In or Out by clicking on the respective buttons under the Filter section. We are able to Hide transactions which are of no interest to us by ticking the check buttons under the Hide section. We are able to view all incoming and outgoing comments, votes, etc. conducted by our account based on the selected period.

What is Author, Curation and Beneficiary Rewards?

Author rewards are derived from content creation itself.

Curation rewards are derived from upvoting another author's work.

Beneficiary rewards are assigned by the author as a means to give acknowledgment for the beneficiaries contribution towards the author's work.

While trying to understand this topic further, I found the below infographic on Pinterest which I think gives a simplified yet detailed picture.
